Abstract
A functional form according to the present invention is disclosed, containing a melt form of a forming resin (Y) compounded with a functional component (a) having antimicrobial properties or deodorizing properties, selected from the group consisting of a catechin, a saponin, a tea-leaf powder, a tea-leaf extract, and tannin (tannic acid), and a ceramics component (b). A process for the production of a functional form is also disclosed, including melt forming a forming resin (Y) compounded with a functional component (a) having antimicrobial properties or deodorizing properties, selected from the group consisting of a catechin, a saponin, a tea-leaf powder, a tea-leaf extract, and tannin (tannic acid), and a ceramics component (b). According to the present invention, the elution of functional components (such as catechins and saponins) can be controlled even after water washing and their functionalities can be maintained (such as antimicrobial properties or deodorizing properties) over a long period of time.
